Definitions

  • Embodiments of the present disclosure generally relate to norbornene homopolymer membranes and their ability to separate natural gas molecules.
  • Natural gas used by consumers is composed almost entirely of methane. However, natural gas found at the wellhead, although still composed primarily of methane, is by no means as pure. Natural gas is typically isolated from three different sources: oil wells, gas wells and condensate well, but whatever the source of the natural gas, it commonly exists in mixtures with other hydrocarbons; principally ethane, propane, butane, and pentanes. Each of these hydrocarbons has a similar size and polarity. Pentane, a larger hydrocarbon, is more easily separated, but for the smaller hydrocarbons, separation is a challenging endeavor.
  • Most membranes used in the gas separation field are derived from glassy polymers and are generally unacceptable for heavy hydrocarbon separations.
  • Most glassy polymers have high permeation of methane relative to propane, butane, and other gases, and these glassy polymers are not sufficiently selective to discriminate between heavy hydrocarbons and methane.
  • Glassy polymer membranes have been used to effectively separate oxygen and nitrogen in air samples, and have also been used to separate butanol from other biofuels; however, these glassy polymer membranes achieve low hydrocarbon selectivity and thus do not provide sufficient separation for natural gas upgrading applications.
  • rubbery polymers such as polydimethylsiloxane (PDMS)
  • PDMS polydimethylsiloxane
  • the glassy polymer membranes tend to show a decrease in performance due to aging. Aging occurs from collapse of free volume, which tends to cause lower permeability.
  • Embodiments of the present disclosure are directed to crosslinked alkoxysilyl polynorbornene homopolymer formulations, methods of making crosslinked alkoxysilyl polynorbornene homopolymer formulations, and methods of membranes incorporating these crosslinked alkoxysilyl norbornene homopolymer formulations, where these norbornene homopolymer membranes demonstrate a high selectivity, suitable permeability, and greater resistance to aging and plasticization, especially in natural gas upgrading applications.
  • Membranes are characteristically subject to tradeoff relationships, where heightened selectivity is accompanied by undesirable decreases in permeability.
  • the pendant alkoxylsilyl moieties of the present crosslinked alkoxysilyl polynorbornene homopolymer formulations maintain high permeability while achieving greater selectivities, which is lacking in trimethylsilyl substituted polymers.
  • prior polynorbornenes utilized in natural gas upgrading applications achieve a lower maximum selectivity for propane over methane (C 3 H 8 /CH 4 ) of 3 under pure gas conditions at 50 psi, whereas the present crosslinked alkoxysilyl norbornene homopolymer membranes may yield at least double that selectivity performance at similar conditions.
  • a method of making a crosslinked alkoxysilyl polynorbornene homopolymer comprising polymerizing a norbornene monomer, having an alkoxysilyl moiety, in the presence of a catalyst to produce an alkoxysilyl modified polynorbornene homopolymer, and producing a crosslinked alkoxysilyl polynorbornene homopolymer through sol-gel initiated crosslinking of the alkoxysilyl modified polynorbornene homopolymer.
  • a formulation comprising a crosslinked alkoxysilyl polynorbornene homopolymer having either of the following structures:
  • R1 is an alkyl, an alkoxy, or OSiR 4 R 5
  • R2 is an alkyl, an alkoxy, or OSiR 4 R 5
  • R3 is an alkyl, an alkoxy, or OSiR 4 R 5
  • R4 is an alkyl or an alkoxy
  • R5 is an alkyl or an alkoxy
  • n is at least one, with the requirement that at least one of R1, R2, and R3, is an alkoxy or an alkoxysiloxane, such as OSiR 4 R 5 .
  • the cross-linking is characterized by 10% to 100% by weight gel content.
  • FIG. 1 is a graphical illustration of the selectivity yielded by different crosslinked ethoxysilyl polynorbornene homopolymers [ROMP-SiMe 2 OEt, ROMP-SiMe(OEt) 2 , ROMP-Si(OEt) 3 ] produced by ring opening metathesis polymerization (ROMP) in comparison to a non-alkoxylated polynorbornene homopolymer produced by ROMP (ROMP-SiMe 3 ).
  • FIG. 2 is a graphical illustration of the selectivity yielded by different crosslinked ethoxysilyl polynorbornene homopolymers [APN-SiMe 2 OEt, APN-SiMe(OEt) 2 , APN-Si(OEt) 3 ] produced by addition polymerization (APN) in comparison to a non-alkoxylated polynorbornene homopolymer produced by APN (APN-SiMe 3 ).
  • FIG. 3 is a graphical illustration of Wide Angle X-Ray Diffraction (WAXRD) patterns of different crosslinked ethoxysilyl polynorbornene homopolymers [ROMP-SiMe 2 OEt, ROMP-SiMe(OEt) 2 , ROMP-Si(OEt) 3 ] produced by ring opening metathesis polymerization (ROMP) in comparison to a non-alkoxylated polynorbornene homopolymer produced by ROMP (ROMP-SiMe 3 ).
  • WAXRD Wide Angle X-Ray Diffraction
  • FIG. 4 is a is a graphical illustration of WAXRD patterns of different crosslinked ethoxysilyl polynorbornene homopolymers [APN-SiMe 2 OEt, APN-SiMe(OEt) 2 , APN-Si(OEt) 3 ] produced by addition polymerization (APN) in comparison to a non-alkoxylated polynorbornene homopolymer produced by APN (APN-SiMe 3 ).
  • FIG. 5 is a bar chart depicting the increase in gel fraction (%) and crosslinking in APN or ROMP, when further conducting the sol-gel initiated crosslinking in acid catalyzed conditions, in this case acetic acid.
  • Embodiments of the present disclosure are directed to crosslinked alkoxysilyl polynorbornene homopolymer formulations and membranes including these crosslinked alkoxysilyl polynorbornene homopolymer formulations, where the membranes have improved selectivity separating smaller hydrocarbons, such as methane, ethane, propane and butane, from a heavy hydrocarbon stream.
  • homopolymer means that the polymer molecule is produced from only one monomer, specifically the norbornene monomers discussed below, and thus does not encompass copolymers comprising additional comonomers.
  • this work could utilize novel copolymerizations to increase free volume and thus the performance of the resulting membranes. That being said, it is contemplated in some embodiments to blend additional components such as additional polymers or additives with the crosslinked alkoxysilyl polynorbornene homopolymer formulation in the membrane.
  • additional components such as additional polymers or additives with the crosslinked alkoxysilyl polynorbornene homopolymer formulation in the membrane.
  • additives could comprise silane small molecule derivatives, which further influence the sol-gel chemistry.
  • high engineered additives such as carbon nanotubes, graphene, or other molecules with metal organic frameworks, would be beneficial in increasing the homopolymer's transport properties.
  • selectivity refers to the separation of larger hydrocarbons in comparison to methane. While the following discussion and examples discuss selectivity or propane relative to methane, “selectivity” as used herein may also encompass other larger hydrocarbons such as butane relative to methane. Pure gas selectivity at 50 psi has been as high as 53 for butane to methane, which is substantially higher than propane relative to methane selectivity.
  • the alkoxysilyl groups of the crosslinked alkoxysilyl polynorbornene homopolymer formulations may provide improved performance to the membrane by increasing the free volume between polymer chains by enhancing steric interactions, as well as promoting gas diffusion due to their high mobility and flexibility. Additionally, the alkoxysilyl containing norbornene polymers are crosslinkable, which offers stabilized performance against aging in long-term applications, while also further increasing the selectivity of the membranes.
  • the membrane selectivities of propane to methane may be 8 or higher under pure gas conditions at 50 psi.
  • the crosslinked alkoxysilyl polynorbornene homopolymer may be produced by polymerizing a norbornene monomer comprising an alkoxysilyl moiety in the presence of a catalyst to produce an alkoxysilyl modified polynorbornene homopolymer. Then, the crosslinked alkoxysilyl polynorbornene homopolymer may be produced through sol-gel initiated crosslinking of the alkoxysilyl modified polynorbornene homopolymer. Various reaction conditions are contemplated for the sol-gel initiated crosslinking. In one or more embodiments, the sol-gel process may be initiated at ambient conditions, or base-catalyzed conditions.
  • the sol-gel initiated crosslinking involves hydrolysis in water or exposure to the atmosphere.
  • the degree of crosslinking may be further increased in acid-catalyzed conditions.
  • acids such as acetic acid, may greatly increase the crosslinking of the alkoxy moieties.
  • sol-gel crosslinking of the alkoxysilyl modified polynorbornene homopolymer may be analogized to the crosslinking of ethoxy moieties in a tetraethylorthosilicate (TEOS) compound, it is contemplated that multiple alkoxy alternatives to the ethoxy may be utilized.

  • the catalyst may be provided with a carrier or solvent, such as toluene.
  • the ROMP catalyst is a Grubbs 1 st Generation catalyst, and may undergo the reaction depicted below.

However, the crosslinking of the present alkoxylsilyl polynorbornene homopolymer embodiments may be controlled such the alkoxylsilyl polynorbornene homopolymer is synthesized, precipitated, and cast into film form before crosslinking occurs.

Establishment of permeation steady-state was verified using the time-lag method, where 14 ⁇ the diffusion time-lag was taken as the effective steady-state.

  • the addition polymerized polynorbornene without an alkoxy achieved a selectivity of only about 3. Referring to FIG.
  • ROMP alkoxysilyl polynorbornene homopolymers [ROMP-SiMe 2 OEt, ROMP-SiMe(OEt) 2 , ROMP-Si(OEt) 3 ] achieve lower selectivity than the addition polymerized alkoxysilyl polynorbornene homopolymers [APN-SiMe 2 OEt, APN-SiMe(OEt) 2 , APN-Si(OEt) 3 ] of FIG. 1 , the selectivity is at least 3 times the selectivity of the ROMP polynorbornene homopolymers without an alkoxy (ROMP-SiMe 3 ).
  • the crosslinked alkoxysilyl polynorbornene homopolymers include at least a first chain packing region and a second chain packing region (illustrated by asterisks), where the first chain packing region is defined by a first interchain distance and the second chain packing region is defined by a second interchain distance, the first interchain distance being smaller than the second interchain distance, where the first interchain distance and second interchain distance are calculated from Bragg's Law for angle peaks measured by WAXRD.
  • the crosslinked alkoxysilyl polynorbornene homopolymers may further comprise a third packing region defined by a third interchain distance, the third interchain distance being larger than the first interchain distance and second interchain distance.
  • the crosslinked alkoxysilyl polynorbornene homopolymers may further comprise a fourth packing region defined by a fourth interchain distance, the fourth interchain distance being smaller than the first, second, and third interchain distances.
  • ethyl vinyl ether (031 mL, 4.51 mmol) was added to terminate the polymerization, and the solution continued to stir. After another 24 hours, the solvent was removed under vacuum in the glovebox until the sample volume was approximately 5 mL, where the sample became a viscous liquid. The viscous solution was precipitated dropwise into stirring alcohol (500 mL). Upon precipitation a fibrous polymer was obtained in a cloudy supernatant. The polymer was dried to constant weight and isolated as an off-white solid.
  • 0.2 mL of the solution containing the palladium catalyst was mixed with 0.2 mL of the phosphine solution, and then 0.2 mL of the trityl borate solution was added to the 0.4 mL of palladium and phosphine. Afterwards, 0.3 mL of the mixed catalyst solution was added to the norbornene solution.
  • the reaction vessel was sealed and brought out of the glove box to heat and stir at 40 degrees Celsius (C) for 24 hour, where it became yellow and viscous. After 24 hours, the solution was precipitated in 1000 mL of acetone dropwise, which immediately formed small white polymer beads stirring in the acetone. The white polymer was collected via filtration and dried under reduced pressure at room temperature.
  • a 0.5 gram (g) sample of triethoxy polymer was dissolved in 10 mL of toluene and stirred until completely dissolved. The solution was then filtered with a 0.45 microliter (4) syringe filters under dry, inert conditions in a glovebox. A 10 mL filtered polymer solution with a 5 w/v % concentration was poured into a 10 centimeter (cm) diameter PFA mold on a level surface. The PFA mold was covered to slow the rate of evaporation, and the film was allowed to dry overnight. Polymer film was removed from the PFA mold and dried to constant weight under vacuum. The obtained films were transparent, ductile and colorless.
  • ROMP-SiMe 3 shows only one peak representing a chain packing of (5.7/7.0) A, which while relatively high is consistent with many diffusion controlled gas separation membranes such as polysulfone or polyimide. Upon ethoxy substitution this peak starts to broaden out in ROMP-SiMe 2 OEt to form two peaks equaling (7.2/8.8) ⁇ and (4.8/5.9) ⁇ .
  • This larger interchain peak is indicative of the high free volume between polymer chains, which allows for solubility-controlled permeation since the chain packing is too large to effectively discriminate between gas molecules.
  • the smaller interchain peak may arise due to the crosslinking of the ethoxy-containing polymers, which is a mechanism for closer packing between polymer chains.
  • the methyl-substituted polynorbornene APN-SiMe 3 is already known in the literature to be a solubility-selective material.
  • This polymer has a bimodal chain packing distribution with a large distant chain-packing region as (13.6/16.6) ⁇ , which was calculated under Bragg's law to be (12.0/14.6) ⁇ .
  • This loose chain-packing accounts for the lack of diffusivity-selectivity in the addition-type polymers.
  • the low scattering angle peak generally shifted to even lower angles as a function of increasing ethoxy substitution, finally reaching (13.4/16.3) ⁇ in the APN-Si(OEt) 3 polymer.
  • APN-SiMe(OEt) 2 (12.4/15.1) actually had increased chain-packing compared to APN-SiMe 2 OEt (12.5/15.3) ⁇ . This unexpected difference may account for the unique transport properties showing that APN-SiMe 2 OEt is a more permeable material than APN-SiMe(OEt) 2 .
  • APN-SiMe 2 OEt and APN-Si(OEt) 3 also showed a third region of very low scattering angle, which corresponds to very distant interchain packing. These peaks represent spacing as large as (40.9/49.9) ⁇ and may be crucial in retaining high permeabilities at heightened selectivities.
  • One of the polymers, APN-Si(OEt) 3 also showed a fourth peak of very tight interchain packing (4.2/5.1) ⁇ that provides evidence of crosslinking in the addition-polymer with the most ethoxy content. Only one addition-type polymer displays this shift compared to three of the ROMP polymers. The higher glass transitions of the addition-type polymers restricts chain mobility and limit the ability of crosslinking sites to react together when compared with the lower T g ROMP polymers.
